The ongoing saga of the PNG Lightning Maroon Clownfish breeding project.

White Stripe Spawn #3 seems to have hatched earlier than expected.  I was looking at the tank on Saturday, 9-13, which would’ve been the day to pull the tile, but the eggs were already gone.  So they may well be on a 5 day schedule?! Meanwhile, Lightning Maroon Spawn #40 was laid on 9-10-2014.  I’ll […]

I skipped worrying about the hatch on the last spawn…we simply have too much going on in our lives at the moment to effectively start rearing a batch of clownfish this week.  Meanwhile, on 9/7/2014, the White Stripe Maroons, the unrelated F0 pairing, put down another nest, but small.  I’ve yet to see a really […]

So I discovered a trick last night – if I run my finger over a clownfish nest, the fish inside the eggs will wiggle if alive. So despite having had no appreciable hatch all day, I pulled the tile, sanitized it again with H2O2, and threw it back in the larval tank.  I DID get […]

Lots going on in the basement. Spawn #33 is almost all through meta at this point, so this afternoon I turned on the system water.  It’s sad that I’ve never used my larviculture system as it was meant to be used by design, but hey, finally, I’m doing it right.  The system water is dripping […]

As of 11 AM, it’s a small hatch on Spawn #34.  I added a little RotiGreen Omega to help keep the fish off the walls, and will check a bit later to see if the hatch has improved during the day.

Spawn #33 – Starting midday on 6/9, the first larvae started showing signs of metamorphosis and settlement; white spots on the heads of the Lightnings are among the first signs; most are through meta today. Spawn #34 – Tonight is the scheduled hatch night; I used the 4 ml H2O2 / 0.5 gallon broodstock water […]

It is now a fact – big Lightning Maroon Clownfish hatches are happening in the morning. I went to bed sometime after 4:30 AM on June 1st, and a few hours later, around 8:30, the kids woke me up. So, I went down to look at the BRT – just a handful of larvae.  I […]

It’s the night of 5/31 going into 6/1/2014, and right before 2:00 AM (6/1) I pulled the tile for the sanitizing H2O2 (Hydrogen Peroxide) dip. While going through the 15 minute treatment at 4 ML per 0.5 gallons of broodstock water, I wiped out the BRT which was used for Spawn #32 and refilled it […]

Based on my calculations, 5/20 is the night we’re due to first have hatches. Having moved all the fry from Spawn #30 into a BRT “on the system”, I wiped down and drained their BRT, and refilled it with water from the Lightning Maroon’s broodstock aquarium. The tile with eggs (huge nest, 4″ X 2″) […]

There are still maybe 2 larvae from Spawn #30 that haven’t settled.  The dice roll so far seems to be heavy towards Lightning offspring…but all told there are probably 10 fish or so that made it. Spawn #31 simply didn’t work out.  The timers on the filtration worked flawlessly, but for some reason the eggs […]
